(CNN) - Pennsylvania Sen. Bob Casey will announce his support of Barack Obama's White House bid Friday, an endorsement that could give the Illinois senator a boost in the crucial primary state that votes April 22.
The official endorsement is expected to come later Friday as Obama begins a week-long campaign-swing through the state. Several recent polls suggest Hillary Clinton appears to hold a double-digit lead there.
Casey is a first-term senator and son of a popular former governor of the state, Bob Casey, Sr. A prominent catholic, Casey's support could help Obama make inroads among catholic voters in the state - a voting bloc that has favored Clinton in most other primary contests.
In 2002, Casey lost a hard-fought gubernatorial primary contest against Pennsylvania Gov. Ed Rendell, now an ardent supporter of Hillary Clinton's White House bid.

I too, was made aware of the California lawsuit against Hillary and I'm wondering what effect it will have on her campaign. It's set for trial in April, so we should see a different look on her face once the media gets it's teeth in to it.
Seems there is a new socialist-style political order presenting itself indeed.
Capitalism is BAD-unless you're a lawyer or politician then greed is good.
Now it is time for Clintons and their supporters to attack Mr. Casy, becasue he chose Obama over them. In their world, America mean Clintons and Clintons mean America and so whoever chooses any other path is Judas.
Thank you, welcome to the movement.
YES WE CAN!!!!
Good for Senator Casey. Shows lots of courage.
Thanks for having the guts to stand up for America, and to stand up for CHANGE WE CAN BELIEVE IN!!!!!!!!!!!!!!!
This contest can be OVER if the PA. voters and more PA. superdelagates will vote and support Obama. PA. voters know that republicans are cross voting and keeping Clinton in the race. Which is keeping her hopes alive.
Good for Senator Casey! He is just one more example of a good man coming out and showing support to say to the public that Senator Obama does not share the radical views of his ex pastor and is serious about bringing people of all walks of life, religions, etc into the political process. I'm certain Senator Obama is proud to have his endorsement.
he is probably trying to get at Gov. Rendell. Stupid step if you ask me.
Finally people realized Hillary has more PA's backings due to her coattailing the name Clinton! I am also very afraid if it is she who should pick up the phone at 3 am sleep-deprived and misspoke.
why does it always sounds like obama is running against ( the clintons ) meaning 2 people. this endorsement is good news, i hope it makes significant inroads in pennsylvania sinces the clinton's feel this is their baby to win
Scott: you forgot to mention that the Clintons invented the internet.
I suggest in the next election Pa vote this guy out.
Do you want a MISPEAKER to answer that phone at 3 A.M.?
I don't think this is going to have a dramatic effect, by any means. And to those that commented from MI and FL, why are you so against the woman that wants to let you revote? Worry about your state, not mine.
Operation Chaos is in full swing!!!!!!
I am afraid if this goes on much longer that the democratic party is going to be destroyed over the Clinton's being willing to do anything to get into power. When you have millionaire's threatening over the Super delegates this is getting bad.
Is he a superdelegate?
Way to go Senator. Thank You!
Hilary wants 800 super delegates a mere 0.0004% of the eligible American voters to chose her as a presidential candidate against the American voters democratic will. How democratic is that?
Excellent decision Senator Casey. May our Merciful Creator continue to bless and help you in your efforts to do good for the people of Pennsylvania and the people of the United States of America.
AT 3AM I would rather have some one who will wait 20 years for his pastor to retire for telling the truth to justify staying put to answer the phone. I wonder how many 3AM calls Obama would miss in the time being.
Way to go Senator Casey, Someone is finally making a stand to try and unify the democratic party so we can win in November.
Did james Carvil (he of the judas betrayal) notice this? Someone inform him.
God Bless you Senator Casey....... Together we stand, divide we will fall.
